APPLYIN Gr PENDULUlVI-POWER.

Specification of Letters Patent No. 19,798, dated March 30, 1858.

To all whom t may concern:

Be it known that I, ANDREW SLEVIN, of the city of Ann Arbor, in the county of lVashtenaw and State of Michigan, have invented a new and useful mechanical application of power, which I style A pendulum power with ratchet movements causing rotary motion,vand designed to be operated upon by a person oscillating the pendulum by means of a rope attached thereto, the same being useful for various purposes where a mechanical application of power is requisite and only a small amount of force can be expended on the same.

To show its relative merits, I have attached to this invention of mine two things to be acted upon: One a churn with the up and down dash by which it may be perceived how this mechanical application of power may be applied, to any thing which requires an up and down motion, by means of the crank R with the connecting rod S tothe projecting arm T from the cross head; the other a circular saw worked by belts and pulleys, thereby showing how this mechanical application of power may be suitable to working saws lathes and other such machinery.

This invention will be especially useful to be applied to churning, in as much as an up and down movement to the dash is the best adapted for the obtaining of good butter; while as a mechanical application of power applied to churning it has no oily parts over the churn thereby doing away with the great objection founded against mostly all other. mechanical inventions for churning. And I do hereby declare that the following is a full, clear and exact description of the same; reference bein hereto had to the annexed drawings (and to the letters of reference marked thereon) making a part of this specication, in which-- Figure l is a side view, Fig. 2 is a front view, Fig. 3 is the bevel wheel I with its pawl U and ratchet V as viewed from line A B in F ige, Fig. 4 is a vertical. transverse section at C D in Fig. 2, and F 5 is the bevel wheel J with its pawl U and ratchet V as viewed from line E F in Fig. 4.

The nature of my invention consists in a pendulum G xed on shaft I-I moving on two friction rollers W one at each end of said shaft H on the frame; on the shaft H there are two bevel wheels I and J fitted loosely to said shaft I-I and gearing into the pinion L on the upright shaft N, V V are two ratchets placed reversely to each oth-er and keyed on shaft II between and next the two bevel wheels I and J; U U are two pawls attached to t-he two bevel wheels I and J and operating on the ratchets V V; K is a bevel wheel on the lower part of the upright shaft N and gearing into the pinion M on shaft Q; O is a fly wheel on shaft Q, R is a crank on end of shaft Q with a connecting rod S, to the projecting arm T from the cross head (not in view) ,the dash being fastenedlto the projecting arm T by means of a thumb screw or nut; Pis a large pulley on shaft Q giving motion by belt to the small pulley X on the shaft Z, Y is a large pulley on shaft Z giving motion by belt to the small pulley on the shaft on which the saw is, and therefore to the saw.

By the oscillation of the pendulum G the shaft H being set in motion, as the pendulum G oscillates one way, the ratchet V operates on the pawl U of the bevel wheel I thereby driving the small pinion L on the upright shaft N, while at the same time the pawl U on the bevel wheel J slips over its ratchet V thereby allowing the bevel wheel J to revolve loose on the shaft H, and as the pendulum G oscillates the other way the bevel wheel J by the same means drives the pinion L and the bevel wheel I revolves loose on the shaft II. This result gives a constant rotary motion by means of the pinion L to the upright shaft N and thereby to the bevel wheel K, which gearing into the pinion M gives a like rotary motion to the shaft Q and thereby to the pulley P which by means of its belt working on the .pulley X on the shaft Z gives motion to the pulley Y which drives the saw (by a belt to the small pulley on the shaft on which the saw is) should that movement be required: or should the up and down movement be required, as the rotary motion is given to the shaft Q it communicates the same to the crank R which by means of its connecting 'rod S to the projecting arm T from the cross head (not in view) gives the up and down motion to the dash.

In this specification I do not declare the relative proportions of the pendulum, bevel wheels, pawls ratchet-s &c. in as much as this depends altogether on the speed and power required; which speed or power can be obtained or lost by changing the respective sizes of the bevel Wheels, pendulum &c. in accordance with the settled rules of mechanics laid down for that purpose.

I am already aware that bevel Wheels, pawls, ratchets pendulum, &c., have been heretofore in use for some mechanical purpose or other and therefore I do not claim any one of them separately. Nor do I claim 10 the bevel Wheels pawls and ratchets causing thereby of themselves rotary motion. But

What I do claim and desire to secure by lLetters Patent is- I. W. H. CULLEN.
